ATTORNEY CARL H. BOLLER, OF KANSAS CITY, MISSOURI.

VENTILATING WINDOW, LOUVEB, DOOR, AND THE Application filed January 16,1917. Serial No. 142,757.

.To all whom it may concern:

Be it known that I, CARL H. BonLER, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in VentilatingWindows, Louvers, Doors, and the like, of which the following is aspecification,

. This invention relates to ventilating windows, doors, louvers and thelike and more especially to that classes of such structures comprising aframe having an opening controlled by an adjustable sash and protectedby a. screen, and my object is to provide a construction in. which thesash is pivoted and the screen lies within the opening of the frameparallel with the sash when the latter is closed and bearing at alltimes an insectproof relation to the pivoted end of the sash, aconstruction of this type being desirable because, it is efficient,simple and inexpensive, can be. installed easily and quickly, conformsin appearance to ordinary screening and in which thescreen member is oflight weight and therefore can be easily handled. 1

With this object in view the invention consists in certain novel anduseful features of construction and combinations of parts as hereinafterdescribed and claimed; and in order that it may be fully understoodreference is to be had to the accompanying drawing in which:

Figure 1, is an outer face view of a ventilating window or the likeembodying my invention.

Fig. 2, is a vertical section of the same.

Fig. 3, is a similar section of the frame for holding the sashes andscreen members.

. Fig. 4, is a fragmentary vertical section of a modified type ofconstruction.

In the said drawing, 1 indicates a frame which may be the frame of anordinary a house window or a frame set at any part of a building. whereventilation is desired, and said frame is rabbeted at its inner side toproduce an inwardly facing shoulder 2 against which to secure arectangular sash frame 3. This frame 3 is provided in the upper half ofits inner face and in the lower half of its outer face with rabbets 4.

Fitting within said frame centrally of its length and journaled in anysuitable manner in the sides thereof, is a rock shaft 5. For conveniencethe rock shaft is shown as hollow and having heads or ends 6 providedwith trunnions 7 journaled in bearing openings formed conjointly in thesides of the frame 3 andremovable caps 8 as shown in Fig. The rock shaftconstitutes the pivot of the window sash, the same comprising thesections 9 projecting diametrically from and of the same length as thebody of the rock shaft, and filled by glass panes 10, if

the structure is to be used as a window. If it is to be used as aventilator only, at a point where light is not an object, the sections 9may be opaque, that is may consist simply of metal, wood or any othersuitable material.

' The sections 9 are adapted to respectively fit snugly in-the openingof the rectangular frame 3 and each. of said sections is provided withflanges 11 to enter the rabbets of said frame 3 and by abutment againstshaft 5 that the structure is insectand.

weather-proof at such oints. The special construction of the screenmembers 1s unimportant and has not therefore been described in detail,it being desirable to state however, that the rails at the inner ends ofthe screen frames are concaved slightly at their point of engagementwith the rock shaftto insllilre a good weather-tight relation therewit 7With a construction of the type described, it is obvious that thepivoted sash can be ad-' justed as desired without interference by thescreens and that any part of the structure can be readily removed andreplaced. It is also obvious that the structure possesses-the featuresof advantage enumerated as desirable in the statement of the object ofthe invention, and, that it is susceptible of modification in minorparticulars without departing from the principle of constructioninvolved or from the spirit and scope of the appended claim.

I claim:---

A ventilating structure, comprising a suitable frame forming an openingand having an inwardly facin shoulder, a sash frame secured in saidopening and against said shoulder and provided with rabbets in itsopposite ends and faces, a rock shaft extending across said sash frameand journaled thereon, imperforate sash sections projecting from saidrock shaft in opposite directions and adapted respectively to engage therabb'ets in the opposite faces of said sash frame, and screen memberssecured to the sash frame at opposite sides of said rock
